Answer:

A=12 ; B= 13

Step-by-step explanation:

37-25= 12

This '12' is A, because there are TWO A's in the first equation and ONE A in the Second equation making the First A/B cancel out leaving ONE a left with the number 12. After you apply A=12 in the second equation you will find B is 13. You can check this by substituting for the first equation

A=12 ; B=13

A=12 B=13 because 12+12+13=37 so 12+13=25
